Application filed October 25, 1912. Serial No.727,756.

To all whom t may concern Be it known that I, MICHAEL J. KLLA, a citizenof the United States, residin at Lorain, in the county of Lorain and tate of Ohio, have invented certain new and useful Improvement-s in Lubricator-Valve Mechanism, of which the following is a specification. Y

This invention relates to improvements in valves, and particularly to valves of the automatic check type.

The invention comprises, generically, a casing, a sliding seat therein, and a flap valve carried by the seat and movably connected therewith to shift to and from a seat-engag ing position relative to movements of the sliding seat.

The invention further comprises, more specifically, the combination, with a casing, of a slidin seat therein recessed to accommodate a ap valve, and a flap valve movably engaging the seat, the face of the seat being concaved from its outer portions toward the point of contact of the liap valve when seated.

The invention also comprises the combination, with a container and a casing eX- tending therefrom, of a valve seat slidingly mounted in the easing, a. tubular extension projecting from the valve seat into the container, said extension being formed with an opening adapted when the seat is shifted toward the container to move into position for receiving fluid from the container, and a iap valve movably connected to the seat in position for closing communication through said tubular extension.

The invention still further comprises certain other novel constructions, combinations and arrangements of arts, as will be hereinafter specified and c aimed.

in the accompanying drawing: Figure 1 is a longitudinal vertical central section through a valve mechanism embodying the features of the present invention. Fig. 2 is a transverse section taken on the plane indicated by line 2-2 of Fig. 1 and looking upwardlv. Fig. 3 is a longitudinal vertical section taken on the plane indicated by line 3 8 of Fig. 1 and looking in the direction indicated by the arrow.

Referring to the drawing by numerals, 1 indicates the container adapted to contain Huid lto be distributed and controlled, as for instance lubricating oil for the cylinder of an internal combustion engine. Pendent from the cover of container l is a tube 2 which extends wit-hin the container to a pointV adjacent the bottom thereof, and threaded within the tube 2 is an adjusting bolt 3 having its inner end extending sufiiciently within the tube 2 to be adapted to be moved, bythe threading of the bolt, beyond the inner or lower-end of the tube 2, the inner end portion of the bolt 3 being formed with a bore 4 for accommodating the tubular extension 5 of a valve seat y6, the upper end portion of the tubular extension 5 being dimensioned to slidingly iit within the bore 4. The seat 6 is slidingly mounted within 'a casing 7 and snugly fits the same, the said casing being fixed to and pendent from the bottom of the container 1, and a bushing or other suitable annular filler 8 is arranged Within the upper end of the casing 7 and has its bore of a size to snugly accommodate and permit reciprocation of the tubular extension 5, the lower end of the bushing 8 forming an annular shoulder adapted to be engaged bythe seat 6 when in its uppermost position for limiting upward travel of the seat. Filler 8 is threaded into both the bottom of container 1 and into the upper end of casing` 7 and forms the connecting means therebetween. The tubular extensionv 5 is formed with lateral openings 9, 9 adapted, when the extension is in its uppermost position as indicated in dotted lines in Fig. 1, to afford free communication from the container 1 to the interior of the eXtension 5. Below the seat 6, the casing 7 is preferably provided with an internal annular shoulder 10 adapted to form the limit of downward movement of the seat 6, and the casing extends below the shoulder 10 and is adapted to receive a tube or other suitable connection l1 extending to the cylinder of an internal combustion engine for purposes hereinafter specified.

The valve seat 6 comprises a centrally apertured disk having the extension 5 preferably formed integral therewith, but obviously the said extension may be suitably connected to the disk, the said extension projecting upwardly from the upper face of the disk, and the lower face of the disk being formed with a concavitpT 12 and with a transverse groove 13 of slightly greater depth than the concavity. Arranged with, l in the groove 13 is a flapor buttery valve consistingof a' plate 1&1 of a width substantially equal to the width of the groove 13 and snugly fitting between the walls thereof, the plate being loosely sustained by a supporting bolt 15 which extends through the plate and is threaded into the seat G, the bolt having a relatively large head disposed beneath the plate. ylhe late 14 is of a lengt-h sudicient to extend rom the bolt 15, at one side of the bore ot said seat 6, to the opposite side ot said bore.

While the valve structure thus tar set forth is particularly adapted for lubricating systems especially designed for supplying a lubricant to the cylinder of an internal combustion engine, the structure is obviously of general application and the spirit of the invention comprehends the adaptation thereof to the various useful arts, but for purposes of illustration the specic use in conjunction with the operation of an in ternal combustion engine will be stated. Assuming the parts to be in the position indicated in full lines in Fig. 1 at the-'time ot an explosion within the cylinder with which the tube 11 communicates, the pressure fluid from such explosion ascending the tube 11 and striking the flap valve and seat will close the valve and lift the seat, the extent of upward movement oli the seat being, oi? course, dependent upon the relative amount of pressure, suilicient pressure beingrequired to overcome the weight of the seat, valve and connected parte. As soon as the valve seat and connected parts begin to move upwardly the openings 9 begin to adord communication between the container 1 and the bore of extension 5 and continue to aittord such communication so long,n as the valve seat remains elevated, which ot course in the illustrative embodiment under con sideration will be as long as the pressure remains in a given cylinder. .fis soon as the cylinder exhausts, however, the valve seat 6 is free to drop and with the intake tor the cylinder the valve seat will be suclted downwardly, the valve 141 being also drawn the suction to its open position if it has not already tellen by i@gravity to such position. lhus the charge of lubricant just taken in through .the ports or lateral openings 9 is left tree to pass the valve 1d, blowing across part ot the groove 18 and down into the tube 11. lt is to be noted here that the provision oit the groove 18 enables comparatively sensitive action ot the flap valve, the extent ot movement of auch valve beine," controlled by the extent to which the bolt 15 is threaded. Furthermore, the concavity in the lower face of the valve seat allows a tree passage ot the lubricant into the tube 11, and insures the draining of all fluid troni noemen the valve seat even after the valve has been closed. lt should be apparent that the bolt 3 is especially adapted for adjustment relative to the extension 5, the extent to which the lower portion of the bolt projects below the tube 2 governing the extent oi' opening' of the ports 9, whereby the quantity ot lubricant admitted at each reciprocation of the valve seat may be e'ectively adjusted.

Having thus described the invention, what is claimed is:
